<h2 class="heading2">Using Event Tracking Mechanism</h2>
<p class="bodytext">The Event Manager is designed to help you organize data interchange between Plesk and external systems. It works the following way: you create a script to be executed upon a certain control panel event, and then create an event handler that triggers the event processing. You can assign several handlers to a single event.</p>
<p class="note"><strong class="buttons">Important:</strong> Plesk administrator can create the event handlers that will be run on the server on behalf of user root. If you wish to restrict usage of the root account, create an empty file with name <code class="monospace">root.event_handler.lock</code> in the location <code class="monospace">/<code class="monospace">plesk_installation_directory/var/</code></code>.</p>
